I think your only choice is to use XP Mode or your favorite form of virtualization.
I think I was successful in a HyperV virtual machine (WinXP 32 bit), but had trouble with communications. The emulator would run, but HyperV was confused about what to do with comms and I didn't succeed with any other software "talking" through my real PC LAN card...This I believe is a HyperV/my IT issue, and I plan to bug them (IT) for a WinXP license so I can try the trusty VMWare system next.
Last week when I emailed tech support to tell them that the emulator was flaky in 502, I also inquired about the emulator and 64 bit, and I was told that they don't yet have any time line for it.
